Laudator Temporis Acti

G.K. Chesterton (1874-1936), "On Modern Controversy," Illustrated London News (August 14, 1926), in his Collected Works, Vol. XXXIV: The Illustrated London News 1926-1928 (San Francisco: Ignatius Press, ©1991), pp. 142-146 (at 145):

We shall soon be in a world in which a man may be howled down for saying that two and two make four, in which furious party cries will be raised against anybody who says that cows have horns, in which people will persecute the heresy of calling a triangle a three-sided figure, and hang a man for maddening a mob with the news that grass is green.

Erik Routley (1917-1982), in James T. Como, ed., C.S. Lewis at the Breakfast Table and Other Reminiscences (New York: Macmillan, 1979), p. 35:

Sometimes some learned men would produce a defense of agnosticism or an assault on Christianity. That was the signal for Lewis to reply. I heard him deliver extempore a satisfying devastation of such an attempt by A.L. Rowse, a distinguished man of letters. "Mr. Rowse", I recall Lewis saying, "reminds me of a friend of mine called Bulver, whose wife has perfected what I call the technique of Bulverism. When Mr. Bulver remarked to his wife that the three angles of a triangle together add up to 180 degrees, Mrs. Bulver replied, 'You say that because you're a man.'"
